Mind reading robot teacher built
A new mind reading robot teacher has been created that stops you from snoozing during lessons.
Tech whizzes in America say it uses special sensors to monitor a student's brain signals while they learn.
When the brain signals dip down, indicating that the student's not concentrating as much, the system sends a message to the robot.
The robot then raises its voice or moves its arms around on screen to get the student's attention back, just like a real teacher might do!
